v z Lns'rld-Frulo,Toss ng f0 all uihom i t may conce tna- Be it-known that I, CHAR ns-W. DAKE, a city/{pf Grand Rapids, county of Kent, State 'chigan, have invented certainnew and useful Improvements in tion.

tiona This invention-relates to improvements in elastic-fluid turbines, g to improvements in' turbine-wheels with see buckets and the means of retaining 1 such sectional buckets in position I positivel sition for operation,

'ing of such shape that .tion.,

" following specification.

The invention is clearly defined ,and pointed out in the claims. A structure embodying the features of my cross-sectional I The object of this a means, of securing invention is to provide the sectional buckets in place, which will whentheparts are tightened secure them in their required 0- can be readily formed and forced into posi T Minor objects and details of construction will definitely appear from the detaileddescription to follow.

I accomplish the objects of my invention by the; devices and means ustrated in the accompanying drawings, iorming a part of this specifichtion,in which Figure 1 is one of the bucket-Se ments for my lmproved turbine-wheel. ig. 2 is a detail view through the segments anda'portion of the Wheel-web of my referredc'onstruction, and Fi 3 is a sumdetail illustrationof a mo ified form of the structure.

In the drawings similar numerals of refer- ,ence refer to similar parts throughoutthe several. views.

'The wheel-web 6 is of course circular in form. The periphery of this is of dovetail form, it being possible to readil turn the same into this shape in any suitab e lathe.

The buckets 5 are semic rcular pockets and are cutobliquely into the re -dents 1 and 1' for receivin the jets and tu n ng them backwardly. T e shank of each segment is prefirably formed with a shoulder to fit against p j Specification of Letters Patent. '1 Application filed nov mherea eoa Serialllo-EBEBBG? and residing at the Elastic-Fluid Turl bines, ofjwhich the following'is a specifica and more particularly a the sectionsand disk e i the various sections objects relating to the described in the.

The projecting parts forming the on the opposite segments are slightly sepa-. rated from each other and are not of siifiicient width to contact with a'ch other around the periphery of the web. I

a Transverse bolts extend holes 3"'and clamp the segments to thepppo embrace the peripheryof as wheel-web; shoulders through suit-able 1.:

site ,sides'of, the wheel-web. 'Whenth bolts are drawntight, the parts'wedge down onto the dovetailed portion and. fit securely into .1,

lace of forming the shoulders in :the". they may lie forr ned in the pears in Fig; 3 ,f t will draw the e shanks of the segments sefse me'ntsl and 1' vsi es of the wheel-web 6,'asa when the clam ing of the b0 lower ends of th curely into place against these shoulders, an-f choring' proper relation to the turbine; Of course vthis method ofifasteningcan be used with other styles of buckets or vanes Withoutjde-f parting froih my invention, a 4 The details of my .structurelcan be modified without departing therefrom. I claim as new, and desireto secure ters Patent-,is-.
